A963158NU Ideal Standard Thermostatic Cartridge

SUMMARY

Ideal Standard A963158NU Thermostatic Cartridge for Concealed Shower Valves

Ideal Standard A963158NU thermostatic cartridge for the older IDEALTHERM Junior and IDEALUX Junior concealed mixer valves listed below.

The cartridge regulates the hot and cold water mix to control the outlet temperature. It is the internal temperature-control component, rather than the separate on/off flow headworks or a complete shower valve.

Before Ordering

Check the full valve reference and production period, not just the IDEALTHERM or IDEALUX name. Compare the original cartridge reference, body shape, control connection and fixing arrangement. The G 1/2 designation alone does not establish fitment.

A963158NU Installation

Isolate both hot and cold water supplies before removing the cartridge and follow the valve manufacturer's servicing instructions. After fitting, check for leaks and confirm correct temperature control before use.
